Physico-chemical characteristics of wheat distiller’s grain with solubles sourced from a Saskatchewan fuel ethanol plant

There is still very limited information on the physical and chemical properties of dried distiller’s grain with solubles (DDGS) derived from wheat-based fuel ethanol production. As this coproduct become increasingly more available in Western Canada, baseline information on its properties is essential in responding to problems posed by existing processing, handling, storage, and transportation systems. This paper presents initial results on selected physico-chemical characteristics of wheat DDGS obtained from a Saskatchewan ethanol plant. These include particle size and size distribution, bulk and particle densities, frictional, compression, and moisture sorption characteristics, all determined at varying moisture levels. Proximate analysis and gross energy determination were also carried out using standard laboratory methods.
